PAPER BAG.

Specification of Letters Patent.

Application filed March 20, 1909. Serial No. 484,674.

To all whom it may concern:

Be it known that I, MATTHEW VIERENGEL, a citizen of the United States,residing at the borough of Brooklyn, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in PaperBags, of which the following is a specification.

My invention relates to an improvement in paper bags having an innerlining of moisture proof paper.

The object of my invention is to provide a paper bag of duplex form inwhich the outer bag is formed of a single blank folded upon itself toform two sides and a bottom, with flaps projecting from one of the sidesfolded inward, and an inner bag with one side of smaller marginaldimension than the corresponding side of the outer' bag, similarlyfolded, with the marginal edges on one side of both bags secured to theflaps of the outer bag.

The features of my invention will be more fully set forth in thedescription of the accompanying drawings forming a part of thisspecilcation, in which Figure l, is a plan View of the outer bag blank.Fig. 2, is a plan view of the inner bag blank. Fig. 3, is a View of thebag in a partly formed position illustrating one side of each inner andouter bag partly secured to a relative side ap of the outer bag, withthe opposite edges of the bags in open position. Fig. 4, is a sectionthrough a completed bag.

The bag is formed of an outer member or bag consisting of a blank withthe sides l, 2, of equal dimension, folded along the medial transverseline 3. The side 1 is provided with the laterally extended aps 4, eachadapted t0 be folded inward along the line 5. The inner blank hasthe'sides 6, 7, adapted to be folded upon themselvesalong the transverseline 8. The side 6 is of the same dimension asthe side` l, of the outermember, while the side 7, is of smaller dimension than the side 2, ofthe outer blank. Thus when the parts are placed and folded together, theouter side 2, will overlap the side 7, with the edges of both sides 2and 7 overlapping the flaps 4, and pasted together. The side 6, alongits marginal surface, adj acent to the surface of the side l, ispreferably asted so as to retain the two members together. Likewise thefree edges of the outer and inner sides 2 and 7, are preferably pastedtogether along their marginal edge.

With this construction of duplex bag it will be seen that all the edgesof the outer and inner bags are relatively secured together, therebyforming a very strong bag and lessening lthe liability of the partsbecoming detached.

Having described my invention, I claim 1. A paper bag formed from anouter blank and an inner lining blank, the outer blank comprising twosides of equal dimensions with a medial line of fold, securing flapsextending from one of said bag sides, an inner blank comprising twosides with a medial line of fold, with one of the sides of equaldimension as the side of the adjacent outer bag, with the opposite sideof the inner bag smaller in width than the adjacent side of the outerbag, whereby one overlaps the other and both overlap the securing flapsto which they are secured, and the remainder of edges` of both bagsrelatively secured together along a marginal line thereof, substantiallyas described.

2. A paper bag of duplex form, an outer blank folded upon a medial line,an inner blank folded upon a medial line, each blank forming two sidesand a bottom, flaps eX- tending from one of the outer bag sides, the

inner bag formed with one side of smallerv marginal dimension than thecorresponding side of the outer bag and with the marginal edges of saiddifferential sized sides of both bags secured to the flaps .of the outerbag, substantially as described.

In testimony whereof, I have hereunto set my hand.
